Omalizumab

Alladapt Immunotherapeutics, a well-financed biotech working in the food allergy field, shut down following talks with the FDA, according to a source familiar with the company. After claiming success in a Phase 1/2 trial in June 2023, Alladapt prepared for a Phase 3 of its experimental food allergy drug. Codenamed ADP101, the oral candidate had received the FDA fast track tag for mono- and multi-food allergies. But a late-stage trial proved too financially daunting. The “FDA guidance for the Phase 3 trial made it economically unviable,” according to the source, who confirmed the company closure to Endpoints News on the condition of anonymity. Investors got a “partial recovery on their investment,” the source added. The Menlo Park, CA-based startup was co-founded in 2018 by CEO Ashley Dombkowski and Kari Nadeau, a former Stanford allergist and now chair of the Department of Environmental Health at Harvard School of Public Health. Dombkowski didn’t respond to an Endpoints inquiry. Alladapt disclosed a $119 million funding round in June 2022 and a $50 million loan with Hercules Capital two months later. The biotech disclosed construction of a manufacturing facility on the outskirts of Philadelphia the year prior. The facility was expected to be completed in “late 2024,” according to architecture and engineering firm Genesis. The company’s investors included Patient Square Capital’s Enavate Sciences, Gurnet Point Capital, AllerFund, Red Tree Venture Capital, Novartis and others. Its equipment was listed for auction in July. Rock Creek Advisors, a firm that works on liquidations and restructurings, lists Alladapt as a client on its website. Some of its top executives left this year for posts at Eccogene and Navigator Medicines . The food allergy space has been through a series of ups and downs in recent years. Nestlé’s attempt to market a peanut allergy drug — known as Palforzia, from its $2.6 billion Aimmune acquisition — had failed commercially. There was a major win in February with the FDA approval of Novartis and Genentech’s Xolair for children and adults with one or more food allergies. Novartis had also axed a peanut allergy Phase 3 trial earlier this year, but said it expected to start a new study of the anti-inflammatory, dubbed ligelizumab, later in 2024. With its ADP101 candidate, Alladapt aimed to deliver small bits of protein from the “big nine” food allergies — milk, eggs, wheat, fish, shellfish, peanuts, tree nuts, soy and sesame — so that patients wouldn’t be as sensitized to the allergens. The startup also terminated an open-label extension study this year. Also in the food allergy space are Leaps by Bayer-backed Ukko and Regeneron, which is testing Dupixent combined with its hematology drug linvoseltamab in Phase 1 .

Nov. 15, 2024 -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the resubmission of the supplemental Biologics License Application (sBLA) for Dupixent® (dupilumab) to treat adults and pediatric patients aged 12 years and older with chronic spontaneous urticaria (CSU) whose disease is not adequately controlled with H1 antihistamine treatment. The target action date for the FDA decision is April 18, 2025. The resubmitted sBLA is supported by data from the multi-trial, LIBERTY-CUPID Phase 3 clinical program (Study A, Study B, and Study C) for Dupixent in CSU. The sBLA adds results from Study C, which was conducted in patients with uncontrolled CSU who were on standard-of-care antihistamines. Study C, the second LIBERTY-CUPID pivotal trial in biologic-naïve patients, met its primary and key secondary endpoints confirming results seen in the previous Study A. Results showed Dupixent significantly reduced itch and urticaria activity (itch and hives). Safety results in all LIBERTY-CUPID Phase 3 trials were generally consistent with the known safety profile of Dupixent in its approved indications. Adverse events more commonly observed with Dupixent (≥5%) compared to placebo were injection site reactions and COVID-19 infection. CSU is a chronic inflammatory skin disease driven in part by type 2 inflammation, which causes sudden and debilitating hives and recurring itch. CSU is typically treated with H1 antihistamines, medicines that target H1 receptors on cells to control symptoms of urticaria. However, the disease remains uncontrolled despite antihistamine treatment in many patients, some of whom are left with limited alternative treatment options. These individuals continue to experience symptoms that can be debilitating and significantly impact their quality of life. More than 300,000 people in the U.S. suffer from CSU that is inadequately controlled by antihistamines. The LIBERTY-CUPID Phase 3 study program evaluating Dupixent for CSU consists of Study A, Study B, and Study C. Study A and Study C were conducted in CSU patients who were uncontrolled on standard-of-care antihistamines while Study B was conducted in CSU patients who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab. Dupixent has been approved for CSU in Japan and the United Arab Emirates (UAE) and is also under regulatory review in the European Union based on earlier trial readouts. Outside of Japan and the UAE, the safety and efficacy of Dupixent for CSU has not been fully evaluated by any regulatory authority. Dupixent, which was invented using Regeneron’s proprietary VelocImmune® technology, is a fully human monoclonal antibody that inhibits the signaling of the IL-4 and IL-13 pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of type 2 inflammation that play a major role in multiple related and often co-morbid diseases. Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, CSU, and chronic obstructive pulmonary disease in different age populations. More than 1,000,000 patients are currently being treated with Dupixent globally.1 Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. This includes REGEN-COV® (casirivimab and imdevimab), Dupixent, Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation. In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
